Rechner Calculator iPhone App: Gestural Arithmetic

This cool little calculator app for the iPhone uses gestures, kind of like how Clear works. It’s definitely an interesting way to use a calculator, one that initially seems a bit counterintuitive, but ultimately it’s supposed to be a bit faster than punching in numbers with your fingers.

Rechner Calculator (Rechner actually means calculator in German) is somewhat ingenious. It’s also minimal, because most of the buttons have been replaced by basic gestures. Adding and subtracting is reminiscent of the way Clear works for tasks.

The Rechner Calculator app is available at the App Store for $0.99(USD). It looks pretty interesting, especially if you tend to make a lot of calculations in the day and you need to use your phone for this.
